Since the advent and mass deployment of flat-panel plasma and LCD monitors just a few years ago, the new application and technology called digital signage has developed great new legs. Estimates of these types of screens being used for the many forms of digital signage in the U.S. as of early 2008 are at almost 500,000. Industry researcher, The Carmel Group, estimates revenues of more than $2.5 billion by year-end 2010. Yet, there is a good chance that the real stride in those legs will develop only if North Americaâ€™s broadcasters join the small band of local operators that are today making digital signage a part of their overall business model. These would include broadcasters such as Capitol Broadcastingâ€™s Jim Goodmon, whose company, Microspace, began focusing on digital signage in 1994, in the form of digital signage kiosks.
